Abstract
Glucocortkoids with hydrocolloid dressing occlusion have been reported to be effective in the treatment of different clinical forms of psoriasis. However, relapse may occur early and therefore it was considered of interest to study the effect on relapse intervals of subsequent short-term PUVA. In a randomized crossover design it was shown that clobetasol propionate ointment occluded with a thin hydrocolloid dressing for 12 days was a rapid and effective symptomatic treatment for chronic palmoplantar pustular psoriasis. However, additional short-term PUVA did not improve treatment results and did not increase intervals between relapses.
